AC, DC, and hybrid control strategies for smart microgrid application: A review

Abstract

Smart microgrid concept-based AC, DC, and hybrid-MG architecture is gaining popularity due to the excess use of distributed renewable energy generation (DRE). Looking at the population demand and necessity to reduce the burden, appropriate control methods, with suitable architecture, are considered as the developing research subject in this area. Previously, a huge volume of literature related to the control strategies of the microgrid (MG) architecture are discussed; however, a systematic and coordinated literature review of the hierarchical control methods based on different MG configuration are discussed very less. In this proposed approach, the control hierarchy of the MG system is divided into three sections as primary, secondary, and tertiary approaches. A brief literature review of the primary, secondary, and tertiary approaches is addressed for respective MG structures. In addition, the manuscript presents the highpoints of state-of-art control techniques with individual merits and demerits. Furthermore, the future trends in the MG control from the presented literature review are analyzed and related simulation study is also presented to provide an additional contribution in this field.
